Assertion [A] : All chemical reactions in a living organism, collectively, is called metabolism.

Reason [R]: Respiration is the best example for anabolism.

• A. [A] is true and [R] is false.
• B. [R] is true and [A] is false.
• C. Both [A] and [R] are true and [R] is the correct explanation to [A].
• D. Both [A] and [R] are true but [R] is not the correct explanation to [A].

Answer 1

The correct option is A

[A] is true and [R] is false.

Metabolism is the set of life-sustaining chemical processes within the cells of living organisms. These enzyme-catalyzed reactions allow organisms to grow, reproduce, maintain their structures, and respond to their environments.

Catabolism is the set of metabolic pathways that break down molecules into smaller units. Eg : Respiration.

Anabolism is the set of metabolic pathways that construct molecules from smaller units. These reactions require energy. Eg : Photosynthesis.
